Understanding the OSI Model: Networking Fundamentals - Lesson 2a

Module 1 of the Networking Fundamentals course will illustrate the core of networking: How data moves through the Internet. The foundation of that is understanding the OSI model. But this isn't about mere memorization, instead we are going to look at the underlying goals of each layer of the OSI model, and how it contributes to the over all goal of networking: Moving data between hosts.
